Hepatocyte TrkB Acts as a Gatekeeper Against MASH‐Related Liver Fibrosis by Suppressing the TGFβ/CCL2 Axis and Macrophage Infiltration

open access: yesCell Proliferation, EarlyView.
Hepatocyte TrkB is identified as a critical gatekeeper against MASH‐related fibrosis. Mechanistically, TrkB inhibits the TGFβ/SMAD3/FOS axis to suppress CCL2 secretion, thereby blocking pathogenic macrophage recruitment and ameliorating liver fibrosis.

Inducible tomato defences persist in detached leaves, despite differential plant variety and gene‐dependent expression

open access: yesEcological Entomology, EarlyView.
Short‐ and long‐term expression of PPO‐D, PI‐IIc and PR‐1a were assessed in intact plants and detached tomato leaves of two varieties infested with Tetranhycus urticae. Tomato defences were induced in both intact and detached leaves, but the induction levels varied with plant variety and gene assessed.

Regulation of PHOX2B gene expression by the long non‐coding natural antisense RNA PHOX2B‐AS1

open access: yesThe FEBS Journal, EarlyView.
PHOX2B is a transcription factor essential for autonomic nervous system development. We identify and characterize PHOX2B‐AS1, a human long non‐coding antisense transcript at the PHOX2B locus, along with its murine counterpart. Our findings reveal bidirectional transcription and reciprocal regulation: PHOX2B activates PHOX2B‐AS1, whereas PHOX2B‐AS1 ...

H2‐dependent modulation of tetrahydromethanopterin S‐methyltransferase (Mtr complex) activity by the small protein MtrR in Methanosarcina mazei

open access: yesThe FEBS Journal, EarlyView.
Small protein MtrR is a regulator of the Mtr methyltransferase complex in Methanosarcina mazei. It binds specifically to the MtrA subunit and modulates Mtr activity in response to hydrogen (H2) availability. Deleting mtrR impairs growth in the presence but not absence of H2, indicating its role in directing methyl transfer toward an energy‐conserving ...

Steroidogenic compensation and lipid deficiency with enhanced NAD+ salvage in small‐for‐gestational‐age placenta

open access: yesThe FEBS Journal, EarlyView.
Fetal growth restriction is associated with placental metabolic adaptations. In small‐for‐gestational‐age placenta (SGA), cholesterol receptors and steroidogenic enzymes are upregulated, enhancing steroidogenesis. NAD salvage pathway is also increased to support NADP+/NADPH requirements.
